this is bbc news. the headlines: donald trump says he's willing to let a partial government shutdown last for months or even years unless he's given $5 billion to build a border wall. the shutdown has left hundreds of thousands of federal workers without pay. talks between the two sides aimed at resolving the standoff were described as ‘contentious‘ by democrats. mrtrump said they were ‘productive‘. a murder investigation and manhunt is under way after a man was fatally stabbed in front of his teenage son onboard a train in surrey. police have described it as "a horrific and hugely traumatic event to witness." the uk has warned russia not to use people as diplomatic pawns, after moscow charged paul whelan, a former us marine with joint british and us citizenship with spying. britain's foreign secretary said the uk had offered consular assistance. now on bbc news — it's time for click.

music plays. yeah, we did all that and more last year and this week we are going to look back at some of our favourite moments and also look ahead to what we might expect from 2019, which

doesn't quite roll off the tongue yet, does that? 2018 was a great yearfor yet, does that? 2018 was a great year for sports, yet, does that? 2018 was a great yearfor sports, the yet, does that? 2018 was a great year for sports, the world yet, does that? 2018 was a great yearfor sports, the world cup formula one and, of course, cycling ‘s formula one and, of course, cycling vs_ formula one and, of course, cycling ‘s — france, and we delved the technology behind them all. this yea r‘s technology behind them all. this year's — technology behind them all. this yea r‘s — france technology behind them all. this year's — france is taking place amongst the beautiful mountains as always. there is a big difference this year. technology is playing more of an issue that every four. cycling is becoming technology driven. masses of data can be collected. in sport of fine margins and superhuman endurance those are the key to energy effect its e—commerce strategy, and genzon. the key to energy effect its e-commerce strategy, and genzon. we look at many things, we look at heart rate, power data, their maximum power and their altitude. we see how the riders are building and will average that they to try to build them to be better and stronger

in stage races. how is the data collected and transmitted ? in stage races. how is the data collected and transmitted? this is where these devices come in. this centres on the bikes and real—time location data to a nearby vehicle, which then been set up way following helicopter. it is then sent to the day to drop for real—time analytics. big data truck is where data is analysed, and rich, and visualise for broadcasters and teams. there is even more data for machine learning algorithms to get to work. the depth of data analytics produced from a simple gps device is staggering. contextual data such as 3—d maps, weather, gradient, and right information is also added to bring the data to life. during the race, riders wear earpieces and, following close behind them, is the date a car, where the team analyst is dissecting the date and feeding them live information. what happens in here, it is quite an important place. imagine if you have a commons office when you are trying to fly a rocket to the moon, that little

place in nasa where all the details come in and they come in from all directions, and then we send out one message to the riders. hundreds of datasets are analysed, from competitor captives to live course conditions. we analyse all the clients, the gradients of the claims, the width of the rose, any road furniture, anything coming round a blind corner and there is a pedestrian crossing, all of these things we try to find. 0n the tour de france, with restrictions on sponsorship deals we don't get any heart rate power data, but we do get location, which is absolutely crucial, because we can make decisions much quicker. we are in the race. this is happening. this is light. what are we saying to the riders? with a come on, you have got 250 more metres. around the next corner, the hairpin, it flattens off at 250 metres. we have drink sat 400m. cool down, take your drinks,

we have only ten kilometres to the finish. i can see the psychological impact of that is huge. meanwhile, this lot are busy practising at speed. 0ver meanwhile, this lot are busy practising at speed. over 250 of these trials take place ahead of the season. these trials take place ahead of the season. they make it look easy. but inevitably it is not, as i can tell you first hand. 0h, inevitably it is not, as i can tell you first hand. oh, no. so loud. and it is meant to be so quick. but i clearly wasn't. meanwhile, spence is already living life in the fast lane. thank you. and by the way, this is how you really do it. laughter. this year mercedes has got its pit

stop down to an incredible 1.85 seconds. that is quicker than it ta kes to seconds. that is quicker than it takes to say 1.85. it's a finely tuned operation that the engineers practice over and over in the days before each race stuck it is a bit ofa before each race stuck it is a bit of a ballet. the ergonomics are very important. there are 20 odd people around the ca rtright important. there are 20 odd people around the cartright to do a job in two seconds. you start banging into people you lose half a second, a second, then the strategists can't get their numbers right and you don't get the position you need. the human element to this ultrafast manouba is technology individually developed by each team. even the hydraulic wheel guards are closely guarded secret. and hear they are quite expensive. they are expensive. we are changing internal is a great

deal. do i hear about £30,000 each? i would not know the exact cost, but that sounds like a load to me. we are going into mercedes' garrard is now. keeping the pit crews safe is of utmost importance. these lights let the crew know if the cars have become electrified, stopping them from getting more than a nasty shock. at this year's world cup finals in russian, —— russia, data is set to play a bigger role than ever before. like it or not data is already an integral part of modern football. you can't watch a televised game without being bombarded by all kinds of statistics. for the first time, fifa are providing an all in one technical package allowing coaching staff and technical package allowing coaching staff a nd a nalysts technical package allowing coaching staff and analysts to communicate throughout matches in real time. the snappily titled electronic

performance and tracking system will provide data on player metrics, such as distances run, speed, and positional information. crucially, each of the 32 countries competing in the tournament will be provided with cue tablets, one for a data a nalyst with cue tablets, one for a data analyst in the stanz, who will be able to communicate with the second device user on the bench, possibly a coach or an assistant manager. level one. lucy staniforth is captain of sunderland ladies and were shortlisted for the women's fa goal of the year. cheering row. the game realism is spot—on. the defender close to me, ifelt real pressure. even fine tuning little skills. i think some of my touches went outside the box, i was not happy with that. working on that, it

is all good. another incredible development is being able to put yourself in any position in any game. obviously where raheem sterling is, he is a farce play anyway, he has the advantage. as the ball is coming in the defender would have too turned their hips and try to clear it that way, i suppose. lucy is watching a real match that took place between manchester city and monach. she can place itself in any position on the pitch, in the sta nz, any position on the pitch, in the stanz, on the roof, and even become the manager —— monaco. stanz, on the roof, and even become the manager -- monaco. right nowl have a clear view of what went wrong in terms of the left back‘s position. you see more detail on the players because position than you would watching match video?” players because position than you would watching match video? i think so. would watching match video? i think so. you are on their level. there is so so. you are on their level. there is so much level in appreciating what they saw. and after a year of great sporting stories, you can see

exactly how my ball skills have improved. it's the last minute of the world cup final and this penalty will win it. can he handle the pressure? here he goes. applause. right, after —— off to japan now, one of the most exciting places we travelled to every year, because we don't know what we are going to buy nevilton yes, robots, of course robots, but not just nevilton yes, robots, of course robots, but notjust robots. you know what it is like you are stuck behind a car and you can't overta ke stuck behind a car and you can't overtake because, well, you just can't see beyond that vehicle. well, this car might be able to help you. it's fitted with a demonstration of a new technology called extra view

and it means you can see through the car ahead using its camera rather than yours. the vision is that the live stream from cameras on our cars will be able to —— be available to eve ryo ne will be able to —— be available to everyone within a certain area. the forthcoming 4g cell network will make this tech more accessible. imagine not having to guess what could possibly be holding you up. lucky escape. now, another thing that may be of interest to japan's ageing population is these. they may look like normal glasses, but if i dress the touch sensor on the side, you may have seen a little flash, and what that was was liquid crystals inside the glass is shifting orientation and changing the focus, meaning it's is to see things close up, just like both late —— bifocals. the upside to these is you can then turn them off and it goes back to your regular prescription. this could be one of the standout technologies of seatech this year,

the ability to detect cancer through a your own sample. the party they can detect cancer in its early stages. it was breast—cancer, lung cancer, for bowel cancer, and also for some childhood cancers, paediatric cancers. initial tests look very positive. bevan had a small sample at the moment, so more testing needs to be done. —— they have only had. how long will this ta ke to have only had. how long will this take to get into surgeries will be the question everyone is asking. such important development. injapan we are thinking one or two macri is to get through the formal stages a cce pta nce to get through the formal stages acceptance by the govern. in other countries like the united states, if you touch it is as this could be available to the public within 3a months, certainly by the summer of next of next year —— government. advances in mass spectrometry and machine learning has maybe bio markers in urine that change with cancer more easy to detect. and it

is hoped as reliable as a blood test. now, obviously, it needs a whole lab set up to do the testing at the moment, but the future, maybe five or ten years danny rowe, well, he taji are already talking to a toilet manufacturer to put the testing element of this into toilets —— down the road. every time we go for ap we could get it result to test and check for any early signs of cancer. but then it got slightly more bizarre. you might not expect to see ata bizarre. you might not expect to see at a tech show is a bonsai tree. 0r should i say aid ponce ai. at a tech show is a bonsai tree. 0r should i say aid ponce al. the tree oi’ should i say aid ponce al. the tree ora should i say aid ponce al. the tree or a fancy pot will automatically move towards light that is needs water. i find out what the world needs and then i go ahead and invent it. at least, that's what thomas edison said. look up and see how

natural these skylights look. up until now would we want a fake window be fitting would contain either a blue light or blue glass or perspex. there is actually no blue light behind you. it's two white leds each side with the suspended diffusers, mitsubishi described them as, in between to replicate the way that natural light comes through the atmosphere. they would give us any more information, and they say it is about two to five years away before some late this could be installed in oui’ some late this could be installed in our homes hospitals or even the underground to give us a little bit of extra natural light. it is almost like i'm expecting to see outside. incidentally, that alarmingly realistic fake window trek turned out to be one of the most watched tech stories on the whole of the bbc website in 2018. so clearly it shone

a light on something. anyway, back in august, we sent nick to france to meet a man with a mode of transport that we have had assessed over the last 30 years, but we have never had a chance to ride until now. and it is not this one. that's right, spencer. i have popped down to provence to poke about in a frenchman's barrage. we are in our workshop, it is where we do all our research and development. perform a jet ski world champion, frank has been at the forefront of water powered vehicles for decades. he has been beavering away over the years on several airborne inventions. been beavering away over the years on several airborne inventionslj started on several airborne inventions.” started with this prototype. in 2011, then we built the real one. two years after, i got the idea of the hover board. and then we got the

idea to create this. it is self balancing. you just press the trigger, and you fly. but recently, he has developed a penchant for rocket fuel. this bad boy has five jet engines packed tightly together, the blast franky off into the stratosphere. well, maybe not that high, but it can reach a top speed of 110 mph. you have a plan b for everything. you have planned eight, plan band everything. you have planned eight, plan b and clancy for the electronics, and you have today, plenty and clancy for the engine, and you can lose an engine. so if one of these five engines blows, then... it is still flying. you can lose two engines and it will still be flying. the explosion will be contained by kevlar protection. the

explosion? if it explodes. it can hold someone weighing 100 kilograms at 500 feet for six minutes. at $250,000 a pop, surely they will sell. it is not something we plan to sell. it is not something we plan to sell. why not? ever tried this today, what would happen? with this on the day, you would kill yourself. and from tech from the movies to the techin and from tech from the movies to the tech in the movies, sir peter jackson marked the 100th anniversary of the end of the first world war by giving film from the era a new lease of life. they shall not grow old is a new documentary film about the first world war directed by academy award winner sir peterjackson. using audio recorded in the 1960s and 1970s, veterans of the western front recollect their wartime experiences. you knew what was going on within your division, beyond that you didn't have a clue. these

stories are told over footage from the war which has been painstakingly restored, colourised and converted into 3—d by jackson's tee wingnut films in new zealand. audio has been addedin films in new zealand. audio has been added in places, but the film develops entirely from the soldiers' perspective, in their own words. the stories are told in an imaginative and starkly way. the film clips from the patriotic fervour of veterans' account of their enlistment to war to the brutal and shocking realities of day—to—day life and death in the trenches. some of these stories are told in a surprisingly matter—of—fact way. told in a surprisingly matter-of-fact way. you didn't publish any buttons, you war any uniform, bits that you like, and nobody worried. all that they were concerned with was that you were fit to fight. peterjackson and his team trawled through the 600 hours of audio and 100 hours of film footage divided by the imperial war museum's archive in order to construct the film. vfx wizardry smooths the

movement of the images, removing any jerky pictures. it's a very, very unusual method of storytelling. that struck me straightaway. it feels different to almost any war documentary i have seen in the past. the brief that they gave me was... 0n the surface it was very simple and very wide open. theyjust said you can do anything you want, but we would like you to use our archive film ina would like you to use our archive film in a way that is unusual. so the first idea i had was i will get them to send me some to case scanned material, like three or four minutes, senator new zealand where we have our visual effects department —— 2k. i thought how well can we restore this film? and that blew me away, we were able to restore it way better than i ever thought we could. 2018 was a big dealfor us on click, too, as we took a large outside the uk for the first time, all the way to new

delhi, in india. it was certainly one of the highlights of the year for me. are you well? and for him. but 2018 really does belong to the robot. there were these. cute, huh? these. this is fusion, my new robot backpack. fist bump. and this. deep in the heart of boston's jungle of cables, something stirs. it is a cheetah, and it's off for a prowl. we are starting to see walking robots like this trotting out of

la bs robots like this trotting out of labs around the world. now, the important skill here is not that they can walk a particular route autonomously. they are usually controlled manually using games controllers. no, the amazing skill here is that they can walk and balance as competently as we can, even on the most unforgiving of terrain. 0k, see, that's impressive. 0k, terrain. 0k, see, that's impressive. ok, that slips, lost its balance, and regained its balance. that's the important thing. whoa! how hard is this? very, very hard. people might not know this, because we move our body very easily, but we have to make sure that we have actually three times more neurons the

muscles, so we have about 700 muscles, so we have about 700 muscles, and we are trying to mimic that using only a motor, it is still pretty darn hard. how close are we to robots like this being of practical use, and what do we still need to get right? so i think we're pretty close in terms mobility, like walking around, walking upstairs, and then turn, the harder challenge is still using arms. like, i said this to power plants were some radioactive activity is going on, we don't know if it is real radioactivity, and to get there you have to open doors, and that is not a simple thing, you have to use your arms, and so on. and that is where the autonomous controls fail very, very easily. so how does the cheater compared to the robots that seemed to make all the headlines lately, those from the stable of boston dynamics? allowed as much younger, we have been only doing this for six

oi’ we have been only doing this for six or seven years, so we have been only doing this for six or seven years, so our software we have been only doing this for six or seven years, so our software is very new, but our hardware is better. we are the first ones to use electronic motors to use these kinds of dynamic motors, and boston dynamics mostly use drugs, which is highly inefficient. i think eventually motor based machines are going to be much more useful, safe and cheap and easy to maintain. at oui’ and cheap and easy to maintain. at our electric motors are very different from the electric motors you can find in a factory. those electric motors cannot actually handle impact, cannot conserve energy, but hours of lending, and jumping, and can do quite dynamic stuff. they certainly can, as demonstrated by this exclusive look ata demonstrated by this exclusive look at a previously unseen manoeuvre. you can't hear it, but our cameraman saw them. —— swore then.

that wasn't pretty. yes, but the thing is it recovered and it stayed upright, and i know people that couldn't handle the recovery better than that. and this year, we are going to do it all over again. next week, we will be in las vegas in the world's biggest tech expo, ces, to kick off 2019 with a look at what is coming, from the car world to smarter homes and gadgets galore. we would love you to join us as we try and bring you the highlights of 2019 before they happen. so wish us luck, and we will see you in vegas, baby. hello, once again.

just because a big area of high pressure is dominating the weather across many parts of the british isles, and it's dry for many, it doesn't mean to say that we're all in the same boat. as we see here, quite a transformation in the day, once the cloud peeled away to reveal those gloriously blue skies. but, if you kept the cloud right throughout the day, well, then it was pretty leaden fare, despite the fact, as i say, it was dry for the most part. and here we are, many of us through the course of the weekend, again, largely dry, often cloudy. and that's because there's quite a lot of moisture trapped in the lower levels of the atmosphere, under the influence of the high pressure there. a frontal system will eventually show its hand across the north—western quarter of the british isles. we'll talk more about that in just a second.

so that cloud shield isn't complete, by any means at all, and if it breaks for any length of time into the first part of saturday, you will end up with a chilly start to your day, although there will be some sunshine to compensate. that could well be the case across parts of wales, down into the south—west. but i think, as the morning proceeds, so perhaps some of those gaps will fill in. again, much of england and wales will be cloudy, but dry. the best of the sunshine perhaps to the eastern side of the pennines, up into the eastern side of scotland. temperatures nothing to write home about for the time of year, pretty average, four to around seven, the exception the western isles of scotland. but here, late in the day, the cloud thickens all the while, so too into northern ireland, and you eventually end up with a wee bit of rain. i don't think it's going to amount to very much at all. it's tied in with that weather front, which, as we move from saturday into sunday, will just tumble its way through the area of high pressure, tending to lose what little potency it had. and you'll notice that one portion was away towards the continent, another eventually flicks back towards northern ireland,

so maybe some brightness here for a time, but then the cloud comes back later in the day. enough about the cloud for there to be the odd spot of rain, perhaps, across the heart of england and wales. the best of the sunshine in the day further north across the greater part of mainland scotland. temperatures may be up a touch or two across particularly the south—western quarter, just picking up on more of a south—westerly flow. but, as i take you from sunday to monday, the eyecatcher is a vigorous area of low pressure passing very close by to the northern portions of britain, before it dives through the north sea and off towards denmark. whilst that's around, and with so many isobars on the charts, it's no great surprise that when i show you the gust values on monday and tuesday for a number of locations across northern and north—eastern britain, well, 50, 60, possibly even 70 mph. not everybody will see that, by any means at all. come a little bit further south and west, a quieter couple of days in prospect. welcome to bbc news — broadcasting to viewers in north america and around the globe. i'm reged ahmad. our top stories:

political lines are drawn over the us government shutdown. democrats and president trump square off as he says he's prepared for it to last months. he said he would keep the government closed for a very long period of time, months or even years. we won't be opening until it is solved. we think this is a much bigger problem, the border is a much more dangerous problem, it is a much bigger problem, it is a problem of national security. us stocks soar after the head of america's central bank says he will adjust interest rates quickly and flexibly — that's despite past criticism from president trump. more tension in kerala, after a third woman defies traditionalists and enters a temple which has been at the centre of a legal battle, keeping women out of the shrine.
